Some experts limit the use of the term “epidemic” to describe diseases that affect humans. To describe diseases that affect plants, the term “epiphytotic” is used, while “epizoétic” refers to diseases in animals. The study of plant epidemics is called “epiphytotiology,” though some mistakenly refer to it as “epiphytology,” which actually refers to the study of epiphytes. While “epiphytotic” and “epizootic” can be used in certain cases to avoid confusion, it is recommended to use “epidemic” in a broad sense to encompass all types of epidemics.
